Entropy-map SSIM analysis of Salt and Pepper Noise Removal via Recursive Median Filterring
Petr Boriskov, Andrei Velichko
This paper studies the removal of salt-and-pepper (SP) noise from grayscale images using a median filter (MF) within a recursive thresholding algorithm. Denoising performance is as…
Local SVD-Entropy Maps as a Complementary Structural Representation for Full-Reference and No-Reference Image Quality Assessment
Andrei Velichko, Petr Boriskov
We investigate a local spectral-complexity representation for perceptual image quality assessment (IQA) based on Shannon entropy of singular values computed directly from two-dimen…
Recursive Threshold Median Filter and Autoencoder for Salt-and-Pepper Denoising: SSIM analysis of Images and Entropy Maps
Petr Boriskov, Kirill Rudkovskii, Andrei Velichko
This paper studies the removal of salt-and-pepper noise from images using median filter (MF) and simple three-layer autoencoder (AE) within recursive threshold algorithm. The perfo…
Entropy-statistical approach to phase-locking detection of pulse oscillations: application for the analysis of biosignal synchronization
Petr Boriskov, Vadim Putrolaynen, Andrei Velichko +1
In this study a new method for analyzing synchronization in oscillator systems is proposed using the example of modeling the dynamics of a circuit of two resistively coupled pulse…
Electrical conductivity of vanadium dioxide switching channel
Alexander Pergament, Petr Boriskov, Nikolai Kuldin +1
The electrical conductivity of the switching channel of vanadium dioxide thin-film sandwich structures is studied over a wide temperature range (15-300 K). It is shown that the ele…
Electrical and optical properties of hydrated amorphous vanadium oxide
Alexander Pergament, Andrei Velichko, Vadim Putrolaynen +5
Electrical and optical properties of amorphous vanadium oxide thin films obtained by electrochemical anodic oxidation are studied. It is shown that under cathodic polarization the…
